Broadcom introduces PoE power supply device controller BCM59101 and BCM59103
Rich and open (Broadcom) Claim to put out first Ethernets and supply power (PoweroverEthernet, PoE) Series of products, the power supply apparatus (powersourcingequipment, PSE) including two high integration degrees Control device BCM59101 and BCM59103. 4 port PoE control devices of the new are general company, small and medium-sized enterprises (SMB) Or already disposed the basic apparatus of Ethernet used for conveying the pronunciation, image and data and offered the power in house environment. BroadcomPoE solution strengthens the trinity service (triple-play) by conveying the electricity to the basic apparatus of the standard Ethernet Characteristic,at the same time can last network design, last maintenance charge, save time, cost and resource. It is a kind of local area network (LAN) that the Ethernet supplies power Technology, can pass the twisted-pairs (twistedpair) The Ethernet cable offers direct current (DC) The electricity is given the current-collecting device including general company, small and medium-sized enterprises and home network (powereddevices, PDs) . It was the development for power supply of the IP Phone that this has already passed IEEE802.3af canonial technology, through a being apt to expand the method with management, fix to some (wirelessaccesspoints) of wireless network accepting unable / inconvenient to install AC electric socket for VoIP or Offer 15 watts of electricity. And IEEE802.3at task group at present is developing the new specification (based on 802.3af) to the electric wattage of the great --Off-The-Shelf the intersection of pre-IEEE802.3at and solution, can need for a new generation upper voltage come network that work link the apparatus and supply power relatively, for example visual telephone, monitor camera, house network off device / router, retail shop terminal to read apparatus, the intersection of entrance guard and the intersection of card and scanner,etc.. New product including BCM59101 and the intersection of BCM59103 and Ethernet that Broadcom issue recently power the intersection of PSE and control device, support BCM59103 control device of BCM59101 and pre-IEEE802.3at specification of IEEE802.3af, adopt the chip design of one degree of forms of high integration, the looks can reduce the part numbers of 30% than in the competition products and simplify the circuit board to design. Among them BCM59103 directs against more high-voltage wireless, video and security technical field application, can offer and surmount the function that primitive IEEE802.3af specification, every port reach 37 watts of electricity. The new PoE products family of Broadcom includes BCM59101 and BCM59103 two PSE control devices, BCM59101 with high integration degree of industry supports 4 port IEEE802.3afPoE apparatuses, every port transmits the electric quantity and reaches 15.4 watts; First and the highest integration and 4 port pre-802.3at specification PoE assemblies of degree that BCM59103 is industry. BCM59101 is compatible with BCM59103 connecting pin, OEM manufacturer can adopt BCM59101 as having cost-effective, solution based on 802.3af specification, to needing more high-voltage application, BCM59103 replacing BCM59101 offers 37 watts of electricity every ports, extend the application of the Ethernet swap device to some of 802.11n wireless accepting, video and security technical field through strengthening the voltage. Broadcom the intersection of new and Ethernet power control device and compete for different characteristics of the products allly, including the power MOSFET of integration, high-efficiency DC-to-DC control device, AC circuit breaker (disconnect) With LED controlling circuit. In addition, these new PoE control devices have avoided the high power consumptive reaction resistor used in the past, make the whole PoE subsystem reach the industry optimally and distribute thermal performance. BCM59101 and BCM59103 built-in microcontroller (MCU) ,Can also offer dynamic power management in order to satisfy bilaminar sorter (L2classification) With the demand for sequencing control. BCM59101 and BCM59103 all adopt Broadcom technological partner AMISemiconductor (AMIS) The mature upper voltage chip process produces; The new product will go on the market in the near future. Ethernet that Broadcom puts out for the first time supplies power the products BCM59101 and BCM59103 supplied power the device controller has already gone into operation, and begin to provide for customer. The price can be asked for.
